Description

Technical Field

[0001] This invention relates to the field of passive optical devices, and in particular to a device and method for removing the protective cap of an optical fiber coupler. Background Technology

[0002] Fiber optic couplers are mainly used to distribute optical signals from one or more optical fibers to other optical fibers in a certain proportion, or to achieve the functions of combining and splitting optical signals between different optical fibers. Their basic principle is based on optical phenomena such as optical coupling and interference, and uses special optical structures (such as using fiber fusion splicing, micro-optical elements, etc.) to change the propagation path of optical signals to achieve the corresponding distribution or combining effects.

[0003] FC type fiber optic couplers are passive optical devices used to connect optical fibers. In the field of fiber optic distribution frame management and maintenance in the communications industry, fiber optic distribution frames in communication base stations and data centers bear a large number of optical cable line connections, distributions and scheduling tasks. These locations have a large number of fiber optic distribution frames and require regular testing of idle fiber cores. FC type fiber optic couplers are widely used on fiber optic distribution frames to realize the connection and signal transmission between different optical fibers.

[0004] Protective caps on FC fiber optic couplers are used to protect the connectors of FC fiber optic couplers. Fiber optic network systems contain a large number of fiber optic couplers and their protective caps. During idle fiber core testing, the protective caps need to be removed from the FC fiber optic couplers to ensure optical path continuity, reduce optical loss, prevent abnormal reflections, and eliminate the effects of obstruction. However, with a large number of fiber optic distribution frames and FC fiber optic couplers on them, the protective caps are usually removed manually. Therefore, a device is needed to efficiently remove the protective caps from FC fiber optic couplers. Summary of the Invention

This function greatly shortens the testing time of idle fiber cores in the fiber distribution frame, reduces the time and effort required to manually remove the protective caps, and allows maintenance personnel to focus more on other important maintenance work, thereby improving the overall maintenance efficiency.

[0026] 2. During the process of removing the protective cap, the device avoids squeezing or damaging the fiber optic coupler and the pigtails in use through precise control and stable design. This effectively prevents service interruption and equipment damage caused by improper operation and ensures the stable operation of the fiber optic communication network.

[0074] Example 10

[0075] Example 10 provides a method for removing a fiber optic coupler protective cap, using the fiber optic coupler protective cap removal device described above. The method for removing the fiber optic coupler protective cap includes:

[0076] S1. The moving mechanism drives the linkage drive mechanism and the clamping mechanism to move, so that the clamping mechanism can extend out from the inside of the housing.

[0077] S2. The linkage drive mechanism opens the clamping mechanism, aligns the clamping mechanism with the protective cap of the fiber optic coupler, and places the protective cap of the fiber optic coupler inside the clamping mechanism. Then, the linkage drive mechanism closes the clamping mechanism to clamp the protective cap of the fiber optic coupler.

[0078] S3. The moving mechanism controls the clamping mechanism that holds the protective cap of the fiber optic coupler to retract into the housing. The linkage drive mechanism opens the clamping mechanism, and the protective cap of the fiber optic coupler falls into the storage mechanism.

[0079] In the fiber optic coupler protective cap removal device, the rotating component 33 in the linkage drive mechanism 3 adopts a single-axis servo motor, and the driving component 46 in the moving mechanism 4 includes a stepper motor and a driver connected to the stepper motor. The driver and the single-axis servo motor are connected to the power mechanism 8. The control module 82 in the power mechanism 8 can control the single-axis servo motor and the driver to operate independently. The sensor 5 is connected to the control module 82. The sensor 5 can detect the position of the slider 44 in the moving mechanism 4. The sensor 5 measures the position of the slider 44 each time. The control module 82 has recorded the position information of the slider 44 each time according to the length of the storage box 61 in the storage mechanism 6 and the length of the fiber optic coupler protective cap.

[0080] During the removal process, firstly, the control module 82 controls the driver to move the moving mechanism 4, causing the first gripper 21 and the second gripper 22 to move out of the housing 1. Then, the control module 82 controls the single-axis servo to open the first gripper 21 and the second gripper 22, and then controls them to close, clamping the protective cap of the fiber optic coupler. After that, the control module 82 controls the driver to move the first gripper 21 and the second gripper 22 back into the housing 1, specifically to the right side of the storage box 61. Then, the control module 82 controls the first gripper 21 and the second gripper 22 to open, allowing the protective cap of the fiber optic coupler to fall into the storage box 61. Since the control module 82 has recorded and stored the position of the slider 44 when the protective cap of the fiber optic coupler falls, during the clamping process, when the sensor 5 detects that the slider 44 has moved to a specific position, the control module 82 controls the single-axis servo to open the first gripper 21 and the second gripper 22. The control module 82 is a PLC (Programmable Logic Controller).

[0081] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
